_______ process takes place in the leaves photosynthesis
what are some structures of leaves? petiole, midrib, blade, vein, and small netted veins
what is the function of veins? veins support the structure of leaves and help in the transportation of substances to and from the cells in the leaf
why do leaves have a large surface area? They have a large surface area allows the leaves to absorb more light
why are leaves have a then shape? The thin shape gives the leaves a small distance for the carbon dioxide to diffuse in and oxygen to diffuse out
what is the function of chlorophyll? It helps in the transfer of light energy to chemical energy
Stomatas are _____ on the underside of leaves that allow gases to flow through holes
______ is the waxy waterproof layer that reduces water loss in the leaves through evaporation cuticle
The one celled transparent layer of cells that does NOT contain chloroplasts and it allows light to pass through is called? upper epidermis
______ is the single celled layer of the leaf that contains stomatas at regular intervals the lower epidermis
How does CO2 get into the leaf? Leaves have pores known as stomatas on the epidermal layer of the leaf, these somatas are used by the plant to respire
Stomatas are flanked by two _____ cells guard cells
what is the function of the guard cells? To control the size of stomatal opening, thereby regulating the flow of gases and water between the leaf and it's environment
why do most plant close their stomata at night? Plants close their stomata at night to avoid too much water loss
